Why is WHY the Perfect question? Most parents remember those persistent questions from their three-year-old, i.e., “WHY is the sky blue?”… “WHY can’t frogs fly?”… etc. You give the child your best off-the-cuff answer, and with a puzzled look they quickly ask, “WHY?” So, you take another crack at it, and again you hear, “WHY?” Your final answer? “JUST BECAUSE!”
However, that answer doesn’t “fly” in BUSINESS!
root cause in business, the perfect question is also “WHY?”
In fact, professionals of
Six Sigma, also the
Toyota Production System, recognize what any three-year-old instinctively knows. That is … to find the REAL reason for a problem or error … again, the perfect question is “WHY?”
